...(512KB RAM, 10K objects)

Pull this back to 300 entries on Svelte devices...  we also need to reduce
this on non-Svelte devices, but at least right now we desperately need it
fixed on Svelte.

  Handle bad WifiHAL implementation
  Don't allow SCAN_REQUEST broadcast to launch apps

Connections to these networks should only be managed by auto-join. If
we enable these configs then it is possible that the supplicant brings
up an unwanted ephemeral connection that auto-join will immediately
discard, which is wasteful.

This change fixes a bug in Wifi state machine - it unintentionally
enables all the networks and results in connecting to a network that
may not have been chosen by AutoJoinController.

wifi_initialize() may succeed even without any wlan. This crashes
the framework. This change handles such inconsistencies.

This change sets the package to Wifi package for all the timer
broadcasts it schedules. This way, the alarm manager won't wake
up any other apps.

Treat Byte#MIN_VALUE equivalently to a null score curve. This allows a
scorer to define an RSSI threshold below which a network should not be
used. Currently, any non-null score curve will result in us connecting
to a given network regardless of RSSI.

Also, instead of applying a hard-coded dBm boost to the currently
active network, make use of the boost specified in the RSSI curve
itself, allowing the scorer to fine-tune this boost.

When the user requests to connect to a network which already has an
untrusted config, we update the existing config and clear the
ephemeral bit rather than creating a new config. We also maintain the
current connection if that ephemeral config matches the currently
connected configuration, and merely tell the system that the network
is now trusted.

The above also applies for AUTO_JOIN_DELETED networks, which are
similarly filtered out from the list of WifiConfigurations.
